KBI-099 The ending when going on a long business trip leaves his wife alone

My family did not let me know my girlfriend because I was still in school. I was angry and left home and went to my brother's house to ask to stay for a few weeks. Maybe he knew what was going on so he was determined not to let me stay and forced me to go home immediately. Because it was already dark, I was allowed to stay for 1 day and had to leave the next morning. But my sister-in-law secretly let me stay the next few days. She let me stay in her closet and promised not to tell my brother.
During this time, I was close to her. more and started paying attention to her body. Even though I'm over 30, my sister-in-law is still young and "tasty", with a perfect figure, smooth white skin and a big, firm bust that makes my dick hard every time I'm near her.
I started I want to fuck her once, to put my cock in my brother's beautiful wife's pussy...
